[DevOps] dps.sentinel.azure.com no longer responds
Hello, Ive been using Repository connections in sentinel to a central DevOps for almost two years now. Today i got my first automated email on error for a webhook related to my last commit from the central repo to my Sentinel intances. Its a webhook that is automticly created in connections that are made the last year (the once from 2 years ago dont have this webhook automaticly created). The hook is found in devops -> service hooks -> webhooks "run state change" for each connected sentinel However, after todays run (which was successfull, all content deployed) this hook generates alerts. It says it cant reach: (EU in my case) eu.prod.dps.sentinel.azure.com full url: https://eu.prod.dps.sentinel.azure.com/webhooks/ado/workspaces/[REDACTED]/sourceControls/[REDACTED] So, what happened to this domain? why is it no longer responding and when was it going offline? I THINK this is the hook that sets the status under Sentinel -> Repositories in the GUI. this success status in screenshoot is from 2025/02/06, no new success has been registered in the receiving Sentinel instance. For the Sentinel that is 2 year old and dont have a hook in my DevOps that last deployment status says "Unknown" - so im fairly sure thats what the webhook is doing. So a second question would be, how can i set up a new webhook ? (it want ID and password of the "Azure Sentinel Content Deployment App" - i will never know that password....) so i cant manually add ieather (if the URL ever comes back online or if a new one exists?). please let me know.

Issue when ingesting Defender XDR table in Sentinel
Hello, We are migrating our on-premises SIEM solution to Microsoft Sentinel since we have E5 licences for all our users. The integration between Defender XDR and Sentinel convinced us to make the move. We have a limited budget for Sentinel, and we found out that the Auxiliary/Data Lake feature is sufficient for verbose log sources such as network logs. We would like to retain Defender XDR data for more than 30 days (the default retention period). We implemented the solution described in this blog post: https://jeffreyappel.nl/how-to-store-defender-xdr-data-for-years-in-sentinel-data-lake-without-expensive-ingestion-cost/ However, we are facing an issue with 2 tables: DeviceImageLoadEvents and DeviceFileCertificateInfo. The table forwarded by Defender to Sentinel are empty like this row: We created a support ticket but so far, we haven't received any solution. If anyone has experienced this issue, we would appreciate your feedback. LucasModernize security operations to secure agentic AI—Microsoft Sentinel at Ignite 2025

Sentinel Data Connector: Google Workspace (G Suite) (using Azure Functions)
I'm encountering a problem when attempting to run the GWorkspace_Report workbook in Azure Sentinel. The query is throwing this error related to the union operator: 'union' operator: Failed to resolve table expression named 'GWorkspace_ReportsAPI_gcp_CL' I've double-checked, and the GoogleWorkspaceReports connector is installed and updated to version 3.0.2. Has anyone seen this or know what might be causing the table GWorkspace_ReportsAPI_gcp_CL to be unresolved? Thanks!
Trend Micro Vision One Connector Not working
Hi All, Before I get nuked in the comments to raise an issue on the Sentinel Repo. Here me out 😇 Around a month ago, the logs stopped ingesting. A quick snoop around revealed the reason. But I'm not sure if I should raise an issue, or try to fix the issue, risking voiding any future support I can get, since the connector and the app that comes with it are market solutions. Function app was not running due to a dependency issue. Spotted this on the diagnostic logs, under the "exceptions" table. "module named _cffi_backend not found" a python package google tells me, thats used to interact with C code. So logically, I need to find the requirement.txt and make sure the dependency is there. Also make sure the python version on the runtime and Azure matches, The logs were initially flowing as usual . I had completed integrating Trend Micro using Azure Functions based connector around 7 months ago. Worked like a toyota helix until now. So once again, would like to know the community's thoughts on it. ThxxRegistration Now Open for Series "Sentinel to Defender: Your Path to the Unified SOC Experience"

how to connect varonis as a connector in sentinel
Hi, I would like to know the process of how can we connect Varonis as a data connector in sentinel. I understand that by reading this article Azure Sentinel: The connectors grand (CEF, Syslog, Direct, Agent, Custom and more) - Microsoft Tech Community , we can connect Varonis through CEF connector. And I have read the instructions mentioned in the article(https://info.varonis.com/hubfs/docs/splunk-app/Varonis-App-for-Splunk-User-Guide.pdf), This is what I understood, can anyone correct me if any? in Datalert configuration(in varonis), connect Syslog msg fwding by giving the Syslog server IP and port number. create an alert template with Syslog msg alert method. ***by this, varonis alerts/data will be sent to Syslog server**** 3.now, we can connect easily from the Syslog server to sentinel easily by executing a few commands which I'm aware of.
Device Tables are not ingesting tables for an orgs workspace
Device Tables are not ingesting tables for an orgs workspace. I can confirm that all devices are enrolled and onboarded to MDE (Microsoft defender for endpoint) I had placed an EICAR file on one of the machine which bought an alert through to sentinel,however this did not invoke any of the device related tables . Workspace i am targeting Workspace from another org with tables enabled and ingesting data Microsoft Defender XDR connector shows as connected however the tables do not seem to be ingesting data; I run the following; DeviceEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated DeviceProcessEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated I receive no results; No results found from the specified time range Try selecting another time range Please assist As I cannot think where this is failingData Connectors Storage Account and Function App
Several data connectors downloaded via Content Hub has ARM deployment templates which is default OOB experience. If we need to customize we could however I wanted to ask community how do you go about addressing some of the infrastructure issues where these connectors deploy storage accounts with insecure configurations like infrastructure key requirement, vnet intergration, cmk, front door etc... Storage and Function Apps. It appears default configuration basically provisions all required services to get streams going but posture configuration seems to be dismissing security standards around hardening these services.need to create monitoring queries to track the health status of data connectors
I'm working with Microsoft Sentinel and need to create monitoring queries to track the health status of data connectors. Specifically, I want to: Identify unhealthy or disconnected data connectors, Determine when a data connector last lost connection Get historical connection status information What I'm looking for: A KQL query that can be run in the Sentinel workspace to check connector status OR a PowerShell script/command that can retrieve this information Ideally, something that can be automated for regular monitoring Looking at the SentinelHealth table, but unsure about the exact schema,connector, etc Checking if there are specific tables that track connector status changes Using Azure Resource Graph or management APIs Ive Tried multiple approaches (KQL, PowerShell, Resource Graph) however I somehow cannot get the information I'm looking to obtain. Please assist with this, for example i see this microsoft docs page, https://learn.microsoft.com/en-us/azure/sentinel/monitor-data-connector-health#supported-data-connectors however I would like my query to state data such as - Last ingestion of tables? How much data has been ingested by specific tables and connectors? What connectors are currently connected? The health of my connectors? Please help
Microsoft 365 defender alerts not capturing fields (entities) in azure sentinel
We got an alert from 365 defenders to azure sentinel ( A potentially malicious URL click was detected). To investigate this alert we have to check in the 365 defender portal. We noticed that entities are not capturing (user, host, IP). How can we resolve this issue? Note: This is not a custom rule.
Unified SecOps XDR
Hi, I am reaching out to community to seek understanding regarding Unified SecOps XDR portal for Multi-tenant Multi-workspace. Our organization already has a Azure lighthouse setup. My question is if M365 lighthouse license also required for the Multi-tenant Multi-workspace in unified SecOps XDR portal?Issue while deploying Sentienl Rules
I know that when deleting a Sentinel rule, you need to wait a specific amount of time before it can be redeployed. However, in this tenant, we've been waiting for almost a month and are still getting the same deployment error ('was recently deleted. You need to allow some time before re-using the same ID. Please try again later. Click here for details'). I still want to use the same ID ect. Does anyone have any idea or similar issue why it's still not possible after waiting for about a month?
Single Rule for No logs receiving (Global + Per-device Thresholds)
Hi everyone, I currently maintain one Analytics rule per table to detect when logs stop coming in. Some tables receive data from multiple sources, each with a different expected interval (for example, some sources send every 10 minutes, others every 30 minutes). In other SIEM platforms there’s usually: A global threshold (e.g., 60 minutes) for all sources. Optional per-device/per-table thresholds that override the global value. Is there a recommended way to implement one global rule that uses a default threshold but allows per-source overrides when a particular device or log table has a different expected frequency? Also, if there are other approaches you use to manage “logs not received” detection, I’d love to hear your suggestions as well. This is a sample of my current rule let threshold = 1h; AzureActivity | summarize LastHeartBeat = max(TimeGenerated) | where LastHeartBeat < ago(threshold)Log Ingestion Delay in all Data connectors
Hi, I have integrated multiple log sources in sentinel and all the log sources are ingesting logs between 7:00 pm to 2:00 am I want the log ingestion in real time. I have integrated Azure WAF, syslog, Fortinet, Windows servers. For evidence I am attaching a screenshots. I am totally clueless if anyone can help I will be very thankful!Codeless Connect Framework (CCF) Template Help
As the title suggests, I'm trying to finalize the template for a Sentinel Data Connector that utilizes the CCF. Unfortunately, I'm getting hung up on some parameter related issues with the polling config. The API endpoint I need to call utilizes a date range to determine the events to return and then pages within that result set. The issue is around the requirements for that date range and how CCF is processing my config. The API expects an HTTP GET verb and the query string should contain two instances of a parameter called EventDates among other params. For example, a valid query string may look something like: ../path/to/api/myEndpoint?EventDates=2025-08-25T15%3A46%3A36.091Z&EventDates=2025-08-25T16%3A46%3A36.091Z&PageSize=200&PageNumber=1 I've tried a few approaches in the polling config to accomplish this, but none have worked. The current config is as follows and has a bunch of extra stuff and names that aren't recognized by my API endpoint but are there simply to demonstrate different things: "queryParameters": { "EventDates.Array": [ "{_QueryWindowStartTime}", "{_QueryWindowEndTime}" ], "EventDates.Start": "{_QueryWindowStartTime}", "EventDates.End": "{_QueryWindowEndTime}", "EventDates.Same": "{_QueryWindowStartTime}", "EventDates.Same": "{_QueryWindowEndTime}", "Pagination.PageSize": 200 } This yields the following URL / query string: ../path/to/api/myEndpoint?EventDates.Array=%7B_QueryWindowStartTime%7D&EventDates.Array=%7B_QueryWindowEndTime%7D&EventDates.Start=2025-08-25T15%3A46%3A36.091Z&EventDates.End=2025-08-25T16%3A46%3A36.091Z&EventDates.Same=2025-08-25T16%3A46%3A36.091Z&Pagination.PageSize=200 There are few things to note here: The query param that is configured as an array (EventDates.Array) does indeed show up twice in the query string and with distinct values. The issue is, of course, that CCF doesn't seem to do the variable substitution for values nested in an array the way it does for standard string attributes / values. The query params that have distinct names (EventDates.Start and .End) both show up AND both have the actual timestamps substituted properly. Unfortunately, this doesn't match the API expectations since the names differ. The query params that are repeated with the same name (EventDates.Same) only show once and it seems to use the value from which comes last in the config (so last one overwrites the rest). Again, this doesn't meet the requirements of the API since we need both. I also tried a few other things ... Just sticking the query params and placeholders directly in the request.apiEndpoint polling config attribute. No surprise, it doesn't do the variable substitution there. Utilizing queryParametersTemplate instead of queryParameters. https://learn.microsoft.com/en-us/azure/sentinel/data-connector-connection-rules-referenceindicates this is a string parameter that expects a JSON string. I tried this with various approaches to the structure of the JSON. In ALL instances, the values here seemed to be completely ignored. All other examples from Azure-Sentinel repository utilize the POST verb. Perhaps that attribute isn't even interpreted on a GET request??? And because some AI agents suggested it and ... sure, why not??? ... I tried queryParametersTemplate as an actual query string template, so "EventDates={_QueryWindowStartTime}&EventDates={_QueryWindowEndTime}". Just as with previous attempts to use this attribute, it was completely ignored. I'm willing to try anything at this point, so if you have suggestions, I'll give it a shot! Thanks for any input you may have!
